Application filed May 11, 1912. Seri'a No. 696,694.

To all whom it may concern:

Be it known that I, lViLLiAM KELLY, a citizen of the United States, residing' at Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Mixers for Internal-Combustion Engines, of which the following is a specification, refer'- ence beinghad to.l the accompanying drawings.

This invention relates to a mixer' for mixingr the fuel as it is being led to the cylinders of anA internal combustion engine.

The primary object of the present invention is to provide a rotary mixer which will automatically mix the fuel as it isbeing led from the carbureter to the int-alte ports of the cylinders.

A still further object of the present invention is to construct a device of this character which will be inexpensive in the cost of manufacture', strong, durable, reliable in use and 'which may be constructed of any preferred design to lit withiir' the intake pipes of various internal combustion engines' lhereinafter more fully described, claimed and particularly pointed out in the ed drawings in which,

Figure l is a side elevation of an ordinary carbureter connected to the intake pipes of ordinary combustion engines having my invention applied thereto; Fig. 2 is a plan View of the rotary mixer. Fig. 3 a transverse section through thesame; Fig. -lis a perspective view of the lower face of the upper ring; and Fig. is a porspectiveview of the rotary mixer.

Reference now being' had to the accompanying' drawing' wherein l have shown a specific embodiment of the present invention, the numeral l() indicates an ordinary append- 'carbureter which is coupled to 'the intake pipes 1l of the combustion engine as illustrated at l2. It is a well known fact that -carlnireters supply the proper amount of fuel to be fed to the cylinders but they'do not properly mix the same a.nd the main object ol this invention is to provide a rotary mixer between the carbureter and the intake pipe of the engine, whereby the fuel will be properly mixed before entering the cylinder.

This mixer comprises two rings 13 and 14 each of which-have alining apertures formed therein for receiving countersunk screws whereby the same may be securely held together. These rings areof any desired construction and are adapted to be secured within the couplingjl where the intake pipe is connected to the carbureter and they are provided with alining apertures 15 through which the bolts ofthe coupling may be .inserted lin securely holding the same within the intake pipes of the engine. Mounted within these rings is a rotary mixing member 1G which thoroughly mixes the fuel as it .is directed from the carbureter to the cylinders of the engine. This rotary mixer comprises a peripheral rim 17 having mounted therein a plurality of radially extending blades 1S and the outer edges of the rotary member are each provilgled with a wire mesh 19. lt is obvious from this construction that as thc fuel leaves the earburoter it willcntcr the mixer and thereby rotating' the same and the fan and wire mesh will thoroughly mix the fuel before entering the Vintake pipe of the engine.

The peripheral rim 17 of the mixer is' of such a diamete' as to fit snugly within the opening forl'ncd by the rings 13 and 14 and is connected thereto by means of a roller bearing which will permit the rotary member to freely turn as the fuel passes therethrough. rings provided with a segmental angular groove 90 which when connected togetl'ier form a semi-circular annular groove for receiving the ball bearings. The outer periphery of the rim 17 ot the rotary inember is provided with a semi-circular groove 2l and mounted between these semi-circular grooves are ball bearings It will be seen from this construction that the rotary member is allowed to freely rotate between the rings 13 and 14A and the roller bearings provide means for retaining the same within the rings and also provide means to allow the same to freely rotate when in use.

To provide means for lubricating the The inner edge of each of the4 i applied lthereto it will be directed to the means for ythe exterior central portion of the annular grooves forming the race Way for the ball bearings. This diagonally extending aperture 23 has mounted on the inner-periphery thereof screwv threads for receiving an air 'tight screw 25 so as to prevent anyfair from entering the` intake pipe When the mixer is in use. As the oil is applied to the opening 23 it will be directed to the ball race by means of gravity and as the rotary member is rotated the oil will be properly fed to the bearings.

It will be manifest that this mixer may be made of brass or any approved metal and it is ot course to be understood that other minor details or changes as to form and construction may be resorted to that come within the scope of the. present invention Without departing from the spirit thereof.

That I claim is :--l

1. Ina deviceot the character described, the combination of a pair of rings forming a casing, of a mixer rotatably mounted therein, means for rotatably securing the periphery of said mixer Within said rings and radiating blades mounted within said mixer, substantially as described. y

2. In a mixer, the combination of a pair of rings, ot a rotary member comprising a rim, a fan mounted Within said rim an rotatably connecting'the periphery of the rim of said rotary member within the interior ,of said rings, Asubstantially as described.

3. Ina mixer, the combination of apair of rings detachably secured together to form a casing, a rotary member comprising a rim, diameter of said rim beingiless than the interior diameter of said rings, antifricti'onal bearings mounted between the l outer periphery of said rim andthe inner periphery of said rings, substantially as and for the purpose described.

4. In a mixer for internal combustion en; gines, the combination of a casing, of a mixer mounted therein, said mixer compris- Copies ofthis patent may be obtained for ve cents each, by addressing the A Washington, D. C.

ing a rim, radiating blades mounted Within said rim and madeintegral therewith, wire meshes for inclosing said `blades 'and means Vtor rotatably connecting said rimyvith said casing, substantially as de'scribed.

5. In almixer for internal combustion engines, the combination of a casing comprising two sections, each of said sections having anannular segmental groove formed therein, a rotary member comprising a pel annularsemicircular ripheral rim having an groove formed therein, bearing elements mountedgwithin said anniilar groove, a tan mounted Within said rotary member, and means for securingthe sections of said casing together, substantially 'as described.

6. In a device of the character described, the combination of rotary member mounted therebetween, said rotary member comprising a peripheral rim having radiating blades mounted Qtherein and formed integral therewith, a "Wire mesh mounted 'Within each end of said rim tor inclosing said blades, the outer periphery of said rim having an groove formed therein, the said casinghaving an annular sem-icircular groove formed on the inner periphery thereof, bearing. elements Within said.v annular grooves and means for detachably securing the said casing Within the intake pipek o t, the engine,
